What Maximus Does
IN SHORT MAXIMUS ELEVATES VO2 MAX and is the ONLY DEVICE that DOES!
MAXIMUS applies resistance during both the inhale and exhale as you breathe while exercising.
9 levels of resistance from 25% to 96% load.
Breathing only through the device creates controlled CO₂ elevation that directly addresses four limiting factors:
1. Recalibrates chemoreceptors — training your CO₂ alarm to stop firing before the fire is real.
2. Keeps the Bohr Effect working in your favor — CO₂ at the right level means full oxygen delivery to working muscles.
3. Strengthens respiratory muscles — your diaphragm adapts under load, lowering the oxygen cost of breathing so more VO₂ capacity reaches your muscles.
4. Improves lactate tolerance — training your body to function effectively in high-intensity, high-acid environments.

HOW IT WORKS
DART - Dual Airflow Resistance
Technology
Resistance on both inhale AND
exhale during exercise load.
9 resistance levels: 25% – 96% load
during exercise
Breathe only through the device —
every breath in, every breath out
That closed loop creates the
training stimulus
The physiology chain — explain step
by step:
1. Chemoreceptors = your body’s
built-in CO₂ alarm system (sensors in brain & blood vessels)
2. During hard exercise, CO₂ builds
→ sensors fire a panic signal: “breathe faster, slow down, danger”
3. Problem: that alarm is SET TOO
SENSITIVE — it fires too early
(like a smoke detector that goes
off making toast)
4. Early alarm → premature
hyperventilation → CO₂ drops too low
5. Bohr Effect kicks in: low CO₂ →
hemoglobin holds ONTO oxygen instead of releasing it at muscles
6. Result: you’re breathing hard
but muscles are being starved the chain MAXIMUS breaks:
Oversensitive chemoreceptors fire
early → hyperventilate → Bohr Effect works against you → oxygen drops →slowdown → VO₂ max ceiling never reached
Train Your VO2 MAX Now
MAXIMUS is a simple 10 to 60 mins daily tool designed to help you build VO2 Max, recover faster, feel steadier, and build real resilience.

My VO2 max improved approximately 6% in just four weeks, damn good.
Overall, I've noted lower resting HR and increased lung capacity, with generally longer, deeper breaths during normal breathing, likely activating the parasympathetic nervous system, resulting in a calmer mood, lower cortisol, and less tiredness.

Kevin Stout - Competitive Cyclist
I have tried many devices in my years of endurance racing. I've worn backpacks designed to simulate altitude training and slept in oxygen tents.
This product shocked me, I decreased my 10-mile road bike time from 33:20 minutes to 24 minutes; that's A BIG IMPROVEMENT of over 9 minutes.
Maximus allowed me to develop more cardiovascular strength while putting less stress on the rest of my body.

I don't have much time for workouts. MAXIMUS allows me to get a great workout in 20 minutes or less.
I do all HIIT training, allowing me to get 120 to 200 reps per body part with no rest between sets.
A MUST for anyone wanting to increase VO2 Max and Strength.

Chris Reichart, NHL Strength Coach, 1994-2005
As an NHL Strength & Conditioning Coach, I recommend MAXIMUS for on-ice and off-ice HIIT. Sprinting or biking at maximum speed for 30 seconds, followed by 60 seconds of low-intensity jogging or cycling, for 8-10 reps, is a great starting point for improving the lactate threshold. MAXIMUS can help improve players' breathing effectiveness during game situations.

I increased my max watts on Peloton from 457 to 510. My strength increased on the incline bench press +62%, and my stamina increased 39% on pull-ups.
As a certified strength and conditioning coach, I was skeptical about the MAXIMUS at first; however, the premise of how the device could improve performance made sense to me.
I see this device truly setting new performance standards across all sports.

Paul Howe, Biotech Executive
I was skeptical at first, however after several weeks of using, I feel as strong as I did in college.
I have seen significant gains in both VO2 Max and Strength. Up 10% on VO2 Max and 30% in strength.
"MAXIMUS is a game changer"!
Setting a NEW STANDARD as an ergogenic aid!

Jamie Mueller, MAXIMUS Founder
Biotech Executive
Former NFL Player
Over 60 weeks now using MAXIMUS, my strength has increased by over 100% on average, and my endurance increased by 50%.
Resistance breathing during exercise has enhanced my fitness and stress management.
I've benefited greatly from this device by increasing my strength and endurance, VO2 Max, and Lactate Threshold.

While I cannot be sure that MAXIMUS will add years to my life, I can assure you that it has added life to my years.
I shaved 30% off my cycling time in the 2.5 miles I typically sprinted through. I've also managed to Increase my strength by +27% on average across all exercises.
I've also noticed Improved concentration, better sleep, improved memory, and an overall sense of well-being.
A must-have If you are at all fitness-savvy.
